I also can't seem to stay logged into my Opera account.

No problems here.

Yes. I can sign in just fine from the Forum front page, but then the browser "freezes" on the redirect page. I have to manually click on the redirect link, which does take me to the Forum but I am not logged-in anymore. Turns into a vicious cycle.

I just installed Opera developer 47 over a fresh copy of Win 10. I can't adjust many of the settings including: On startup, Cookies, Images, JavaScript, Flash, Pop-ups, Location, Notifications, WebRTC, Handlers, etc. I also can't seem to stay logged into my Opera account. I had to go to Vivaldi to log into the forum and post this message!

Dudes! Yeah, I did a totally clean install and it seems to be working now. Thank you for your help, as always.

Did you try a reinstall? What about a clean profile?

No. I haven't reinstalled. This was a fresh install to start with and the behavior was there from the very beginning.

Dude! I'm trying to give Opera Beta a chance, but here's the infuriating problem I am running into. When I click on a link from a search page, nothing happens. If it's a Google search page, the tab kind of flickers. If it's a Yahoo! search page, clicking opens a new blank tab. In fact, I couldn't get to this help page in Opera Beta. What's going on?

So, I am using Opera developer 44. When I click on a magnet link, nothing happens. :o

What happens if you disable hardware acceleration?

That fixed the problem. Thank you, thank you, thank you!

What about opera:/gpu? Does it shows any error message?
How the video behaves on Chrome or other Chromium based browser?

opera:/gpu log...http://pastebin.com/Z99wrCtW

There might be a problem, starting with line 23.

Video works flawlessly in Chrome and Vivaldi.

By the way, the problem isn't limited to just this video. Any video from any website seems to display the green overlay.

I think I clicked on the right entry. Does this help?
